| Abstract Scope |
Titanium-Zirconium-Molybdenum (TZM) is a high-performance refractory molybdenum alloy frequently used in aerospace, including rocket nozzles, high-temperature structural components, and radiation shielding. This material has excellent creep resistance and superior strength at elevated temperatures. Despite its favorable properties, fabricating TZM with conventional manufacturing methods remains challenging due to its inherent brittleness and limited room-temperature workability. This research focuses on developing process parameters for TZM in Electron Beam Powder Bed Fusion (EB-PBF) using Design of Experiments (DOE). EB-PBF is well-suited for refractory materials as parts can be built at elevated temperatures through preheating, enabling hot-working conditions. A systematic DOE was employed to optimize key process parameters. Relative density was measured using Archimedes' principle, helium pycnometry, and optical microscopy to validate fabrication quality. Results demonstrate the viability of EB-PBF for high-performance TZM alloy fabrication and establish a foundation for process optimization. |
